Effects of Plant Growth Substances on Biomass and Lipid Production in Diatoms
Zhiguo Ju, Lixiao Ding, Kangjun Li, Zhen Ding, Qingna Zhang, and Yuan Li
Abstract—The effects of plant growth stimulating substances
like naphthalene-acetic acid (NAA), Gibberellic acid 3 (GA3)
and 6-benzylaminopurine (6-BA), or plant growth inhibiting
substances like abscisic Acid (ABA) and [(2-chloroethyl)
trimethylammonium chloride] (CCC), or their combinations,
on biomass and lipid production in Pinnularia gibba var. linearis
and Chaetoceros gracilis were studied. When applied at day 1
(stage I), treatments with NAA, GA3 and 6-BA or their
combinations enhanced biomass production but reduced lipid
contents. The total lipids, however, were higher in these
treatments than that in the control. 6-BA was more effective in
stimulating total lipid production. No difference was found
among the treatments with NAA, GA3 or their combination.
Adding NAA or GA3 to 6-BA did not enhance biomass or lipid
production compared with 6-BA alone. When applied at day 4
(stage II), growth stimulating substances increased biomass
production compared with the control but did not affect total
lipid production. Less biomass was obtained when the
treatments were applied at day 4 compared with that applied at
day 1. Treatments with growth inhibitors like ABA, CCC or
ABA + CCC at day 1 reduced biomass production and total
lipids, although lipid contents were increased by the treatments.
When treated with ABA, CCC and ABA + CCC at day 4 ,
however, they did not reduce biomass production while
increased lipid contents and total lipids.
